I don't dispute any of this. However, the reality is that the province isn't proposing to spend that money on anything. They just said "it's too expensive, please go away" to people with a very legitimate complaint and a long history of being ignored or outright oppressed by that same government.
If the government had approached them and said, "It would cost $200 million and be extremely dangerous to the searchers and the environment. What if we did X, Y, and Z with $200 million instead and named X a memorial to the missing victims?" then this would be a different conversation.
I agree the money could be put to better use, but it's not even being proposed. The money is just being used as an excuse to swat down people that have been swatted down their entire lives.
I'm not a fan of going ahead with the search. The risks to the searchers and the environment (risk of toxic leaching, etc) is too great in my opinion.
However, my opinion here can't matter. This has to come down to the families and advocates. And the government has made NO overtures to them beyond, "gee, that must suck, sorry." So failing a better offer, I don't blame them for continuing to hammer the only point they have available to them.
